Recommendations for Pediatric Dermatology Practice during COVID-19 Pandemic

Area of Science:

• Pediatrics
• Infectious Diseases
• Epidemiology

Background:

• The global coronavirus disease (COVID-19) pandemic impacts all age groups, presenting a significant disease burden worldwide.
• While children can contract COVID-19, they are affected less frequently and severely compared to adults, with over 90% exhibiting asymptomatic or mild to moderate symptoms.

Purpose of the Study:

• To summarize the epidemiological characteristics and clinical presentation of COVID-19 in pediatric populations.
• To identify factors contributing to the differential susceptibility and severity of COVID-19 in children versus adults.

Main Methods:

• Review of existing epidemiological data and clinical reports on COVID-19 cases in children.
• Analysis of potential immunological, genetic, and environmental factors influencing COVID-19 outcomes in pediatric patients.

Main Results:

• Children represent a small percentage of overall COVID-19 cases (2% in those under 20), with childhood cases forming 1-5% of this group.
• The majority of pediatric COVID-19 cases are asymptomatic or mild/moderate, contrasting with adult experiences.
• Factors such as reduced exposure, varying immune responses, differences in Angiotensin Converting Enzyme 2 receptor expression, and potential protective effects of vaccines (measles, BCG) may explain milder pediatric outcomes.

Conclusions:

• Children generally experience less severe outcomes from COVID-19 compared to adults.
• Underlying medical conditions such as cardiac or respiratory diseases, diabetes, immunodeficiency, cancer, or immunosuppression increase the risk of severe COVID-19 in children.
